One-step production of biodiesel from waste cooking oil catalysed by SO3H-functionalized quaternary ammonium ionic liquid

The catalytic conversion of waste cooking oil (WCO) with high acid value (120.37 mg KOH/g) to biodiesel has been studied in low-cost SO3H-functionalized quaternary ammonium ionic liquid as catalyst. The ionic liquid (IL) catalyst was efficient in catalysing the simultaneous esterification and transesterification reactions of WCO and methanol.
